This invention relates `to spring cushion structures.

The main objects ofthis invention are:

`First, to provide a spring cushion structure of Ythe 'type embodying springs-'ofthe bowed zig-Zag type in which Vsuch springs are effectively supported and at the same time may be easily and quickly engaged with the supporting frame.

- Second, to provide a base frame which is very rigid and at the same timemay be formed of relatively light materials and constitutes means for attachment of upholstery thereto.

A structure which embodies the features ofthe invention is illustrated in the accompanying drawing, in which:

Fig. 1 is-an inverted View of -a'springstructure embodying my invention, the topper or mat Vsprings and upholstery being'omitted.

Fig. 2 is an enlarged fragmentary perspective View of the baseframe and oneiend of one of the bowed body springs inoperative engaged position therewith.

Fig. 3 is'an end view oi'the structure shown in Fig. 1 :with portions-'of the'top'border frame shown in Fig. 1 omitted.

Fig. 4 is a fragmentaryplan'view.of a slightly modified embodiment of myinvention.

The structure illustrated is especially designed for the support ofl bowed springs generally classied as Zig-'zag springs-although Ydesirable for use in-supporting other typesof springs. The springs illustrated in the embodiment shown in Figs. '1, 2 and 3 are those illustrated in' the' Stuart Patent No. 2,291,094, issued July 28, v1942. 'In spring structures embodying'springs oftl'iis'zig-zagv type, the Vbase frame or 'frame/on which the vsprings are mounted is subjected to very heavy load stresses and it is important that the frame shall not yspringer be distorted. It is also important to provide a structure'permitting the rapid and 'effective mountingv of l the springs. n'the' struc,-V

tureillu-strated no'consideration has *been given toy din'rrensionsl but itwill be understoodthat the dimensions are Vvaried according to the purpose of thespringfstructure or unit.

"ZI'hef baseA frame-ini the embodiment 'illustrated designated generally i by thev numeral i comprises aifrontimemberi?, rear members andend'members vconstituting the tbottom Amember ,of a

disposed, the tacking strip providing illustrated. The web i of thefbottommemberis :121 Claims. (Cl. 155-179) extended and-folded uponitself to Jprovidethe inwardly projecting double-ply flange', the in ner edgeof the under-ply of this `angelbeing conformed to provide the vinnerfarm -9 of 'the channel.

Tcp members i0 are secured to the-frontand rear bottom frame'members vThese topvm'embers are formed of sheet metal conformedto provide tubular body portions `vll'which are superimposed upon the channel :portions-f5 nof the'bottom members. The edges of theistrip fromwhich the top members are 4formed-'are extended to provide inner and vupper plys I2 of `inwardly Yprojecting flanges I3 which are superimposedl upon the anges of the front andrear members Yand xedly secured thereto 'desirablyfby spot welding as indicated at M. The under-ply of the anges i3 is extended inwardly and turned upwardly and outwardly to provide `spring attaching member i5. These spring attaching `membershave longitudinally spaced holes |26 thereinand notches 'H at each side of and adjacent to the tholes. The body springs |-8 illustrated in Figs. `1,'2 iand3'are of the structure shown in theStuart-patent'here inbefore referred to. These springs are kupwardly bowed vand terminate in varms t9 :which are inserted in the notches 'i"i,--the arms termihating in lugs 20 arranged through'the holes` iB. The body springs I8 may be quickly engaged with the frame land are effectively/supportedthereby so that the frame vreceivesand withstandsthe springing stresses.

It will be noted thattheiront, rearfan'd side members of the bottomframe member are'formed in two sections joined by the couplings f2 l. vThe top Amembers iil are provided Vonlyat the front and `rear of the structure and they constitute effective-reenforcing means-for the base member and also provide means vforv the attachment of the body spring members.

In the modiiication -shownin Fig. 4 the spring elements 22 are single spring elements as distin- 'guished vfrom the double spring elements shown in Figs. 1,2 and 3. The spring elements terminate in arms 23 `whit-.hare disposed through the notches 24 in the spring attaching flange and retained therein by .clamping `the `flange Aaround the arm as indicated at 25. It will be under stood that the body springs are usually provided with a topper 'unit which may be made up in the formof a mat of coiled springs provided with a front :border frame 2,6 constituting what 'is commonly designated Vas a front extension and serving to support the upholstery ,in an Vextended relationto the bottom of the cushion.

The structure illustrated is designed to have the upholstery secured by tacking to the tacking strip or insert.

In the structure illustrated tie or anchoring members 2l are provided at the corners of the frames, these having arms 23 welded to the bottom member of the frame and being secured to the end bowed spring elements by means of clips 29. Spring tie members 3% are provided for adjacent spring elements, the outer spring elements being connected to the bottom frame of the topper assembly by similar tie members 3l.
